is shown arranged to rotate a shaft represented conventionally at 10,and suitably supported by a bearing 11, the latter supported upon asuitable sta-ndard,or other support, not shown. The lmproved devicecomprises a shell like structure including a rear disk-like portion 12having an annular rim 13 secured thereto by any suitable means, forinstance by screws, or like fastening devices as shown in Figs. 1, 2, 3and' t, or'by set bolts 47 as angular supporting members, one of whichis shown in perspective in Fig.- 6. The supporting members are preciselyalike and are interchangeable within the shell.

Each of the supporting members is'indieated as a whole by the character15, and

each provided with a projection. 16 extending from the outer edge andthe remaining edges beveled, as shown at 17 The supporting members 15are so arranged that when disposed within the shell their confrontingedges ares aced apart to formguideways 18, the beve ed edges 17 of themembers 15 forming the sides of the guidew'ays.

7 Four of the members 15 are "employed so that the guideways radiatefrom a common center, asshown in Fig. 1. Eachof the which engage overribs, indicated at 20,

:'which project from the inner face of the portion 12 of the shell. Theguide-slots 19 and the ribs '20 extend inparallel relation'to each otherand at right angles to the outer faces of the members 15, so that thelatter are movable toward and away from'the center of the shell and ofthe shaft 10 and thus control the width of theguideways 18, ashereinafter explained. I

Clamp bolts 23 extend through the memhere 15 and the portion 12 of theshell, and are formedwith countersunk heads engaging in countersunkapertures in the members 15 and provided with clamp nuts 24 bearingagainst the inner face of the member 12. The member 12 is formed withslots indicated at 25 where the bolts 23 pass throu h, so thatthemembers 15 may be ad- ,members 15 is provided with guide-slots'19justed toward and away from'the center of the shaft to any requiredextent within the range of the slots 25, and thus hold the members 15 intheir adjusted position.

Fittin within the spaces between the members 15 and the rim at eachsideof the projection 16, are adjusting blocks26, the inner faces of theblocks bearing flatly against'the outer edges of the members 15 and theouter faces of the blocks curved to correspond to the curvature of theinner face'of the rim 13. Operating through each of theprojections 16 isa clamp bolt 27 upon which adjusting nuts 28 are mounted and operate toadjust the blocks 26 toward and away from the projections 16 to causetheir outer curved faces to bear against the inner face of the rim 13.'By this arrangementit will-be obvious that'the members 15 may beadjusted toward and away from the center of the shaft 10 and thuscontrol :the width of the guideways 18, and the-blocks 26-maybe-likewise adjustedto hold the members 15 firmly in their adjustedposition. The bolts 23 and 27 enable these adjustments to be made, andcooperate to firmly lock the members 15 in their adjustedposition.

Movablydisposed in the guideways 18 are coacting sliding members 29which are formed; as shown in Fig. 8 with beveled sides conforming toand closely engaging the beveled edges of themembers 15. Each of-theslides is provided with a wrist=pin30. Two of the members 29 areemployed and are ofgreaterlength than the width of the guideways- 18, sothat the slides will move past the innerterminals of the: guideways andnotbe deflected from their paths. connecting'rod comprising a stockportion 31 and ahead portlon 32 forms a part of the im roved. device,the head portion being of Sn cient length to engage both of the wristpins '30,'as shown in Fig. 1. The head portion' 32 of the connecting rodis formed with transverse-openings"or guideways 33 for the bearingblocks or brasses which engage the wrist; pins, the guidewaysbeing-separated by aweb .34. Each pair of the bearing blocks or brasseswhich engage in theguideways 33 are precisely alike 'and-the descriptionof oneset-or pair willsufiice for both. The

bearing blocks or brasses for each of the openings-'33 are shown inperspective'in the lower, portionof the group of members represented-inFig. 7 On'e ofthe bearing blocks is represented at 35 and fits'fiatlyagainst the-outer-end-of oneof the-guideways 33 and against the flatinner end of the other guideway33. The other bearingblock orbrassrepresented at 36, fits-within the 'guideway -33 at the oppositesides of the wrist pin's from the member 35 and are formed :with Vshaped portions 37 the V shaped portionsof the twoblocks extendingtoward each other, as shown-in Fig. 1. The

head member 32' ofthe connecting rod is 'clampnuts 42 whereby the keyblocks may the head 32 and the other set'operating through the bottomofthe head; as shown in Fig. 1. The key members '39 are apertured toreceive clamp bolts 41 provided with so be moved toward each other andthus apply pressure to the members 36. By this means the brasses 3536may be adjusted to control th position of the connecting rod 5 relativeto the wrist'pins, and take up lost motion which may occur, and maintainthe parts in adjusted position. Thebolts 41 are preferably provided withjam nuts 43 to prevent the clamp-nuts 42 from working loose.

By thisarrangement when reciprocal motion is imparted by-anysuitablemeans to the connecting-rod 31 rotarymotion will be imparted to theshell member 1213, and a universaladjustment between the. parts securedby simply manipulating the holding nuts 28 and 42;. The improved devicemaybe applied without structural change for driving wheels or devices ofvarious sizes and forms and thus adapt the device to various forms ofmachinery and to machinery employed, for various purposes;

In Figs. 5 and 6 a modification of the construction is shown consistingin an attachment whereby power may be transmitted fromthe rim ofthemember 12 instead of fromthe -shaft' 10. Themodified attachmentconsists in providing the rim 13 with an annular, gear rack 48 and aninwardly directed fiange.49,-the latter bearing against the rear outerface of the member 12 and secured .thereto by set bolts orlike'f'devices 47. The flahge49 is provided with inwardly directedprojections 50,while the ,l remainder-of theflange extends outwardly ofthe bolts 23 and the nuts 24; so th at. the presence ofthe fiange andits projections do not interfere with the operation of the bolts wherebythe members 15 are secured in position. a j
